I am attending an on-line education program in my country. The Mathematics platform looks like the ideal place to make knowledge exchange and for this reason I am interested in knowing if it is aloud to participate in other languages, most of my companions are not English fluent speakers.
If I invite some colleagues.

Questions

a: Can we post questions in Spanish?

b: Can I invite my professors for helping the community answering in spanish too?
